PAPER-PADIDIN G APPARATUS.

Specication of Letters Patent.

Patented Nov. 26, 1918.

Application led May 25, 1917. Serial No. 170,907.

To all whom it 'may concern Be it known that I, ROBERT B. BONE, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have` invented a new and Im roved Paper-Padding Apparatus, of whicli the following is a full, clear, and exact description.

This invention relates to paper padding apparatus or what are known ordinarily as paper padding racks, or racks for holding paper .while being padded.

More definitely stated the invention pertains particularly to a vertical rack having parallel side bars with which cooperate in a self holding manner a plurality of flat plates which serve to prevent horizontal displacement or disarrangement of the paper or stacks of paper being operated upon, while at the same time permitting movement of the paper in vertical lines to allow for the compression that may be applied thereto.

Another object of the invention is to pro vide a vertical frame or rack which includes a vertical board against which the paper may be stacked in ractice in perfect alinement along that e ge or side to which the glue and fabric are applied in the operation of padding, said board being held removably in place so that after the stacking is conipleted the board may be removed. aiordingI direct access to the edge or face of the paper to be padded.

A further object of the invention is to pro vide improved facilities for detachabl y holding said front board in place.

Another object of the invention is to pro vide a rack ot' the character indicated, with means for rotating it around a vertical axis whereby the loading of the rack and the subsequent padding of the paper loaded therein may be accomplished with the rack stationed close to the Wall so that very little Hoor space is required.

Another object of the inventionis to provide a padding attachment adapted for the accommodation 'of stacks of sheets of paper of diiferent sizes at the same time, or in other words for the making of pads of different sizes simultaneously, the holding means or the devices for preventing the lateral or longitudinal displacement of the sheets being adapted to operate just the same whether the sheets are all of the same size or not.

`With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in` which like reference characters designate the same parts in the several views, and in which- Figure 1 is a side elevation of my improved apparatus, the rack being filled with a stack of paper and having the front thereot' turned toward the wall.

Fig. 2 is a view in elevation of the opposite side of the rack with the front turned away from the wall and the front board unfastened ready for removal.

Fig. 3 is a front elevation with the front board removed.

Fig. 4 is a plan view with the parts shown in the position in Fig. 1.

Fig. 5 is a detail perspective view indicating one of the corner pieces and the relation of the lower end of the front board thereto.

Fig. 6 is a plan view of the rack bottom indicating in dotted lines the position of the front board and also indicating sheets of paper of different sizes being manipulated.

Fig. 7 is a detail perspective view of one of the holding plates; and

Fig. 8 is a detail plan view of another forni of holding plate and the coperating vertical bar in horizontal section.

Referring now more particularly to the drawings I show a paper paddin apparatus comprising a rack or frame aving a bottom or base 10, vertical parallel side bars 11 and 12 and a top cross bar 13. The base is supported upon a turntable 14 having a central pivot 15 in a foot piece 16 secured or supported upon the Hoor of the building in any suitable manner. The axis of this pivot is vertical and lies Within a vertical plane substantially central of the two side bars.` The cross bar is formed with a hole for a pivot 17, the axis of which is in vertical alinement with the axis of the pivot 15 and is carried by a Wall bracket 18 of any convenient type. The foot 16 and the bracket 18 are so located that the rack may swing vfreely around the vertical axis of the two pivots and will be held so that it is not liable to tiltin any direction from said axls. Asshown best in Fig. 1 the front edge of the base 10 lies slightly ahead of the vertical plane of the two front edges of the side bars 11 and 12, but said base 'extends rearwardly to any' desired distance beyond the rear edges o the bars so as to 'Iirmly support large sheets of paper or stacks of paper to be padded. he cross bar 13, however, extend-s forwardly as indicated at 13 to a certain distance beyond the front edges of the side bars.

At the lower front cornersoi' the rack or frame are located a pair of corner pieces 19 and 20, the rear ends of which are secured to the side edges of the baseer to the lower ends of the bars 11 and 12. These corner pieces provide definite -ock-ets or seats for the lower corners of a ront board 21 having a perfectly flat or true inner snrface, the upper end of which is adapted to bear securely against the front edge of the cross bar or portion 13 of the cross bar 13. This board is adapted to be locked temporarily in this perfectly vertical position by means of an convenient hooks or hasps 22 carried by the side bars and adapted to eooperate with eyes 23 carried by the front board. When the rack is constructed andassembled as described herein and is turned with the front toward the Wallfas shown in Fig. 1, piles or stacks of paper to be padded are placed directly upon the base 10 and piled in this manner with two adjacentedges lying-squarely against ythe smooth flat inner face of the 'front board and the inner surface of one of the side bars. Since Vthese two vertical surfaces are at exactly right angles to each other the sheets of paper 4applied thereto in perfect order may be retained in such order by contact with said surfaces. If desired a stack or pile of paper of a larger or smaller size, or even of the yseme size as the onefirst referred tofmay be piled '-upon the base simultaneously with the first mentioned pile or stack. The innersureee of the other side Ahar is bron ht into action inthis connection along wit the inner surieee ofthe-frontboard. (See Fi 6).

The lacing ofthe ,piles or stac s oipaper upon 't e base andagainstthe vertical front board and side bars, or loading of Ithe rack as it isfcalled in practice, is accomplished fronrtherear offthe rack while the front thereof is turned toward thefwyall. en a stack of suitable height is loaded u on the Vbase `means it is necessary to retain t e same `in stable ,position For this pur ose l.[,pro-

vide a series of .holding plates 2 i, as shown ,in `detailin Fig. 7, -each ofwhich hasend notches or .extensions having positive connection fwith the side bars 11 and 12. .The plates 24 are shownshavi 'notches-25 which :receive fthe .side bars t erein while the=exte sions 261lie on oppositesides of .the

'-bars. i Qithoutthese lockingplatesilhfor sini-:winst 'le ,me @faire www be liable to spring or bulge laterally with the result of a tumbling or spilling thereof if the Stack were high enough to represent an economical transaction. In other words forthe'ap aratus to be useful in the greatest economy or space and the making of a hi h stack for the economical application of t e .glue rand fabric thereto it is essential that a considerable number of these locking plates be employed to prevent the tilting, bulging or other lateral displacement with respect to the flat front board.

'fter the slack ol sheets to be padded has reached the desired height, or a plurality ot stacks have been formed and llrwlred from lateral displacement as above indicated, the operator places a weight 27 upon the topinost plate 24 which will serve to put the entire stack or stacks under suitable compression and hold the saine temporarily un til the padding operation is completed. The operator then swings lhe rack around through an are of a circle according to his convenience, as for example through 180O as shown in Fig. 2, bringing the front of the apparatus remote from the wall. He then, While the weight is still in place holding the stack and locking plates steady, will remove the front board by first unhooling the hasps 22 and then lifting the board vertically ont of the corner ieces 19 and 20. From the construction ofthe lower part of the appa- Iatns the edges of the paper to be treated with glue and fabric are all free or clear of the rack structure so that the yglue may be applied readily to the entire fro-nt face of the stack of paper, covering all portions of the edges of the paper to be reached, and yet without danger or necessity Jfor smearing the glue upon any portion of the rack. In this connection also it is to be noted that the plates 24 may be of such a width vasto stop a triie short of the plane of the front board so that the front e es of the looking plates need not be smeare with the glue. These plates 24 .may be made of anysuita'ble material or'thickness for their purpose but I sugest for this purpose the use of No. 25 .gage s eet metal, t e thickness therefore of which is not great enough to disturb the vertical alinement of the front edges of the paper which may overlap the same. After the board is removed the glue isspread over the entire front ytace ofrthe stack, andthe-'strip of fabric is applieddirectly thereto and if desired another coat of glue-may be applied over the fabric, depend-ing upon the particular requirelnents of any s. ecial lieb.

.After thegglue hasdried Ithepa, dedpaper 1 may 4beremoved from the rack, first removfthe convenient or well known manner. Y l In zlflig.4 8 :I .snggesta femmy oft-side. r 11 having a vertical groove 11al into which a lug or tongue 26 of a different form of locking plate 24 majyT project. The bar 11', however, may be of the same general dimensions in cross section as the bars 11 and 12 above referred to so that the plates 24 may be employed in connection therewith, if desired, as well as the plates 24.

AS shown in Figs. 1 and 2 to the rear face of the front board 21 and on opposite sides of the smooth flat portion thereof against which the paper is stacked, are secured a pair of studs 21 which are adapted to bear against the front edges of the side hars 11 and 12 to hold the bottom end of the front hoard snugly against the outer ends of the corner pieces. The length of these studs is exactly equal to the extension 13 or that part of the cross bar 13 which projects forwardlyv of the front edges of the side bars.

I claim:

1. In a paper padding apparatus, the combination of a frame comprising a base, a pair of vertical spaced parallel side bars eX- tending upwardly from the base and a cross bar connecting the upper ends of the side bars, means to support the frame for free rotation around a vertical axis, said side bars each having straight parallel front and rear edges, means cooperating with the frame to receive a stack of paper with at least two of its faces in true vertical alinement at right angles to each other, and a series of Hat plates each having end projections engaging slidabl;7 with the straight edges of the side bars to permit vertical movement of the plates but prevent lateral movement thereof and of the stack of paper, substantially as set forth.

2. In a paper padding apparatus, the combination of a frame comprising a base, a pair of upright parallel side bars having vertical front edges, a pair of co-rner brackets extending forwardly from the base and the lower ends of the side bars and a cross bar connecting the upper ends of the side bars and having an extension reaching forwardly of the upper ends of the said front edges, a removable front board having its lower end received in said corner brackets and adapted to lie squarely against the front edge of said cross bar extension, and a pair of studs carried by the side edges of the front board and adapted to bear against the front edges of the side bars to hold the front board vertical.

3. In a paper padding apparatus, the cornbination of a frame comprisinga base, a pair of upright spaced parallel side bars extending upward from the base and a cross-bar connecting the upper ends of the said bars. said side hars each having strai ht parallel edges, means co erating with t e frame to receive a stack o paper with at least two of its faces in planes at right angles to each other, and a series of flat plates each having end projections engaging slidably with the straight edges of the side bars to permit free movement of the plates along the bars but preventing lateral movement thereof and 0f the stack of paper, substantially as set forth.
